The main goal of this course is to introduce students to special radiation therapy and image-guided therapy procedures that are considered “non-routine” or in “advanced” form relative to the current clinical practice and may require special consideration in the preparation and execution. Special procedures are important clinical services which are usually provided directly by the clinical medical physicist. The special procedures selected in this course may change over time. Currently, the following topics are included: image-guided radiotherapy procedures; total skin and total body irradiation techniques; fetal and pacemaker dosimetry; commissioning of IMRT planning systems; 4D CT imaging procedures; CyberKnife treatments; and tomotherapy treatment techniques.
